Channel Occupancy Time Duration for Cell Starting from Downlink Control Information Slot

A base station comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the base station to:
• transmit configuration parameters indicating a plurality of slot format combinations of a cell;
• transmit, during a slot, downlink control information (DCI) indicating a slot format combination of the plurality of slot format combinations, wherein the slot format combination indicates a channel occupancy time (COT) duration for the cell;
• and
• receive, from a wireless device and via the cell, a transport block based on the COT duration, wherein the COT duration starts from the slot.

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors of a wireless device, cause the wireless device to:

• receive configuration parameters indicating a plurality of slot format combinations of a cell;
• receive, during a slot, downlink control information (DCI) indicating a slot format combination of the plurality of slot format combinations, wherein the slot format combination indicates a channel occupancy time (COT) duration for the cell;
• and
• transmit, via the cell, a transport block based on the COT duration, wherein the COT duration starts from the slot.
